摘　　要：基于河网水流特性,建立了面向对象的通用河网非恒定流模型,根据模型数据驱动运行机制的要求,从关系数据模型的角度对河网模型中各种类型的数据设计相应的数据模式,使不同的计算模型共享相同的实测数据,并结合开源的GIS软件对可视化的计算程序进行分层设计。在长江下游大通至镇江段的应用结果表明,该程序能实现多方案比较,具有一定的实用性、通用性。Based on analysis of river network flow characteristics, an object oriented universal model is established to calculate unsteady flow of river network. According to data driving mechanism and relational data model, the data schemes for various data are established, which makes it possible to share the same observed data in different simulation models. Accordingly, a visual program integrated with opewsource GIS software is designed on the basis of hierarchical framework. Finally, the program is applied to simulate the flow in the reach from Datong to Zhenjiang on the Yangtze River. The results show that the program can compare alternative projects and meet the requirements of practicability and general utilization.
